Examine the wtmp and btmp logs, /etc/shadow (if necessary) and /etc/passwd and
output the desired data.

The optional argument username forces lslogins to
print all available details about the specified user only. In this case the
output format is different than in case of -l or -g and
unknown is username reported as an error.

Mandatory arguments to long options are mandatory for short options too.

-a, --acc-expiration

Display data about the date of last password change and the account
expiration date (see shadow(5) for more info). (Requires root
privileges.)

--btmp-file path

Alternate path for btmp.

-c, --colon-separate

Separate info about each user with a colon instead of a newline.

-e, --export

Output data in the format of NAME=VALUE.

-f, --failed

Display data about the users' last failed login attempts.

-G, --supp-groups

Show information about supplementary groups.

-g, --groups=groups

Only show data of users belonging to groups. More than one group
may be specified; the list has to be comma-separated. The unknown group
names are ignored.

Note that relation between user and group may be invisible for
primary group if the user is not explicitly specify as group member
(e.g. in /etc/group). If the command lslogins scans for groups than it
uses groups database only, and user database with primary GID is not
used at all.

-h, --help

Display help information and exit.

-L, --last

Display data containing information about the users' last login
sessions.

-l, --logins=logins

Only show data of users with a login specified in logins (user
names or user IDS). More than one login may be specified; the list has to
be comma-separated. The unknown login names are ignored.

-n, --newline

Display each piece of information on a separate line.

--noheadings

Do not print a header line.

--notruncate

Don't truncate output.

-o, --output list

Specify which output columns to print. The default list of columns may be
extended if list is specified in the format +list.

--output-all

Output all available columns. --help to get a list of all supported
columns.

-p, --pwd

Display information related to login by password (see also
-afL).

-r, --raw

Raw output (no columnation).

-s, --system-accs

Show system accounts. These are by default all accounts with a UID below
1000 (non-inclusive), with the exception of either nobody or nfsnobody
(UID 65534). This hardcoded default maybe overwritten by parameters
SYS_UID_MIN and SYS_UID_MAX in the file /etc/login.defs.

--time-formattype

Display dates in short, full or iso format. The default is short, this
time format is designed to be space efficient and human readable.

-u, --user-accs

Show user accounts. These are by default all accounts with UID above 1000
(inclusive), with the exception of either nobody or nfsnobody (UID 65534).
This hardcoded default maybe overwritten by parameters UID_MIN and UID_MAX
in the file /etc/login.defs.
